commercial installation where it is really, really important, you put in isolation transformers adjacent to the equipment. that's the most expensive solution but the best solution is to actually put an isolation device right at your equipment. they also have filters that you can buy, but that's a commercial-grade installation. residentially, a dedicated circuit, try to separate it from other wiring to the extent possible. >> anything you might want to add to that? >> yes, they're called a clean circuit. you use the m.c. cable or 12-three, 12-2, the whole circuit. the computer or the microwave. >> so if you can probably do it, it sounds like putting in some kind of metal conduit-clad cable or something that will really reduce the interference. read for me what all these little things mean here.
